Description
Original diagnose after Ward (1979) p. 118 (genus diagnose) and 119 [2493]: (based on isolated lower antero-lateral teeth only). Antero-lateral teeth characteristic of family. Principal cusp commisurally directed, sigmoid, distinctly larger than and almost separated from first distal cusplet. Labial surface of principal cusp strongly convex, lingual surface flat or slightly convex. Distal cusplets commisurally directed, 4-8 in number. Weltonia having principal cusp approximately 50% longer than the first of the five to eight distal cusplets. Gradient monognathic, heterodonty present.
